Cherie Dimaline - Empire of wild (2020) ENG

Broken-hearted Joan has been searching for her husband, Victor, for almost a year - ever since he went missing on the night they had their first serious argument. One hung-over morning in a Walmart parking lot in a little town near Georgian Bay, she is drawn to a revival tent where the local Métis have been flocking to hear a charismatic preacher. By the time she staggers into the tent the service is over, but as she is about to leave, she hears an unmistakable voice.

She turns, and there is Victor. Only he insists he is not Victor, but the Reverend Eugene Wolff, on a mission to bring his people to Jesus.

With only two allies - her Johnny-Cash-loving, 12-year-old nephew Zeus, and Ajean, a foul-mouthed euchre shark with deep knowledge of the old Métis ways - Joan sets out to remind the Reverend Wolff of who he really is. If he really is Victor, his life and the life of everyone she loves, depends upon her success.
